(The grocery store I frequent has never accepted checks as valid payment. I’m in line when this happens.)

Customer: *hands the cashier a check*

Cashier: “Sorry, sir, but the store doesn’t accept checks. Do you have another form of payment?”

Customer: “WHAT?! I’ve been a loyal customer for ten years! I’ve always paid with a check, you lazy teenage b****! You just don’t want to go through the trouble of processing it! F****** [Asian slur].”

Cashier: “Okay, politeness is out. This store has never accepted checks. If you don’t have another form of payment and stop swearing, I have to ask you to leave. Also, I’m in my late 20s.”

Customer: *swears under his breath and leaves*

Cashier: “Well, I guess these go into the return bin.”

Me: “You handled that well.”

Cashier: “I’m the oldest of five; it takes more than a temper tantrum to annoy me.”
